dears,

i have VZ 05 we call it here in Saudi Arabia Lumina SS LS1 engine 5.7

i faced electrical issue couple of days.. i was stopped on red signal, then gauges, CD changer
"all dashboard lights" and front and rear lights goes off for maybe 3 seconds it's happened 2 or 3 at the same time. then its works again with ABS fault for less than a second on screen but the engine is running normally!!

Does this happen only when you have your foot on the brake?

Ok, yesterday i go for testing if it's happening with brakes, and the result was, yes its happen with stiff braking, all gauges and CD came off, one more thing i noticed, the head lights is not stable seems like flickering and this is happening only if the car moving!!

i don't know what it could be? maybe Alternator?

I personally would be looking for a loose/dirty earth connection, maybe near the battery or on the engine block. Sounds like something is shifting when sharp sudden movements happen.
